If your website has a Google Analytics tracking code installed, you are bound to have to share this data with another party at some point.
This other party might be a business partner that needs to keep an eye on website traffic, it could be your AdWords expert that needs to monitor goal conversions, or it might be your search optimization consultant monitoring the growth of your organic traffic.
Irrespective of who you need to share your Google Analytics data with, the steps remain the same.
Here are the steps to add another user to your Google Analytics account
Login to https://analytics.google.com/ with the account you want to share
Click on ADMIN at the bottom of the left hand menu (see screenshot below).
You will see three columns (Account, Property and View). Towards the top of the Account column, click on the User Management option (see screenshot below).
In the Add permissions for section, enter the email address of the user you want to share your data with. I always check the Notify this user by email option, but you can choose not to (see screenshot below). Click on Add, and you are done!
IMPORTANT: I recommend you only give Read & Analyze permission to another user. The other permissions I would be hesitant to give out, unless it is a person that I trust implicitly.
